Resize controls!

Hi Folks!
i am developing a player in flash which you can see here.
http://www.skashif.com/allaboutinnovation/demo/colin/HDplayer_resize.html

i only want the controls to remain of same size as they in normal screen mode when user enter fullScreen Mode.
i am trying a twisted way which i thing may work, that is taking ratio of stageWidth and ScreenResolution and multiplying it with controls height ad width…
i hope that works!:pa:

so i want ask you people to give me some leads.
